      In this chapter, effects of incorporating QDMs into non-benzenoid aromatic or antiaromatic frameworks are discussed focusing on the open-shell, diradical character with respect to their molecular structures, antiaromaticity, and physical properties related to the open-shell character and molecular orbital levels and materials applications, as Cited by: 5.

Though kekulene was synthesized in , it was the only known compound of this class of compounds for a long time. Recently, new kekulene-related molecules, septulene, which is a non-alternant benzenoid hydrocarbon, and a tetracyclopentatetraphenylene (TCPTP) derivative belonging to non-alternant non-benzenoid hydrocarbons, were synthesized.

New York, Interscience Publishers, (OCoLC) Description: Nonbenzenoid Aromatics, Volume II, provides an overview of the state of knowledge in the field of non-benzenoid aromatic compounds. The theme that threads its way through the six chapters is that of ""aromaticity,"" with each author making an effort to.

The Chemistry of Nonbenzenoid Aromatic Compounds — II is a collection of plenary lectures presented at the Second International Symposium on the Chemistry of Nonbenzenoid Aromatic Compounds.

Starting with a review of the synthesis and study of select heterocycles, the book includes results and developments in this area. An Introduction to the Chemistry of Benzenoid Compounds is an introductory text to some chemical aspects of benzenoid compounds.

This book is composed of 13 chapters that specifically cover the sources, properties, and reactions of these compounds. Azulene, which has a specific structure of ring-fused unsaturated seven-membered and five-membered rings, is a typical non-benzenoid aromatic compound.

Whereas naphthalene or other hydrocarbon compounds are generally colorless, azulene, a structural isomer of naphthalene, is dark blue, and the name comes from the Spanish word azul, meaning "blue".

NON-BENZENOID AROMATIC COMPOUNDS AND THE CONCEPT OF AROMATICITY 'pin CONTENTS Introduction Structure of aromatic compounds and nature of + aromaticity The cyclopentadienide anion The tropylium cation The cyclopropenylium cation Azulenes Cyclobutadiene Cyclooctatetraene Pentalene and heptalene   The key difference between benzenoid and non benzenoid compounds is that benzenoid compounds contain at least one benzene ring in the molecule whereas non benzenoid compounds have no benzene rings.

An aromatic compound is a cyclic, planar molecule with a ring of resonance bonds. These structures are more stable than normal ring structures.

This discussion on Difference between benzenoid and non benzenoid aromatic compounds is done on EduRev Study Group by Class 11 Students.

The Questions and Answers of Difference between benzenoid and non benzenoid aromatic compounds are solved by group of students and teacher of Cl which is also the largest student community of Class The chemistry of aromatic compounds was originally confined to benzenoid hydrocarbons and their derivatives but has been enriched in the last decade by the discovery of numerous non‐benzenoid, cyclically conjugated systems that are more or less like benzene in their properties.

This has necessitated a new conception of “aromatic character”.Cited by: The development of the chemistry of non-alternant non-benzenoid hydrocarbons is reviewed in connection with the International Symposium on Novel Aromatic Compounds (ISNA) Author: Yoshito Tobe.

In organic chemistry, benzenoid is a class of chemical compounds with at least one benzene ring. resonance bonds in benzene ring gives increased stability in benzenoids. Most of aromatic hydrocarbon is benzenoid. Notable counterexamples are Cyclooctadecanonaene, azulene and trans-bicalicene.

These compounds exhibit aromatic character and include Azulene, an isomer of naphthalene which serves as a ligand for low-valent metal centers in organometallic chemistry. Other articles where Benzenoid aromatic compound is discussed: hydrocarbon: Aromatic hydrocarbons: stability and are classified as benzenoid aromatic compounds.

Certain other compounds lack a benzene ring yet satisfy the criterion of special stability and are classified as nonbenzenoid aromatic compounds. Aromatic hydrocarbon, are hydrocarbons containing sigma bonds and delocalized pi electrons between carbon atoms in a ring.

For example, benzene. They are known as aromatic due to their pleasant smell. Aromatic Compounds Examples. Aromatic compounds are broadly divided into two categories: benzenoids (one containing benzene ring) and non.
